Constructor & Destructor Documentation

Solver() [1/2]

qpalm::Solver::Solver	(	const ::QPALMData *	data,
		const Settings &	settings
	)

Create a new solver for the problem defined by data and with the parameters defined by settings.

Exceptions

std::invalid_argument

if calling qpalm_setup failed. This may be caused by invalid bounds or invalid settings.

Definition at line 27 of file qpalm.cpp.

Solver() [2/2]

qpalm::Solver::Solver ( const Data &  data, const Settings &  settings  )

inline

Create a new solver for the problem defined by data and with the parameters defined by settings.

Exceptions

std::invalid_argument

if calling qpalm_setup failed. This may be caused by invalid bounds or invalid settings.
